Courtesy Lamp: Description and Operation

INTERIOR LIGHTING
The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses.

The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob

If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off.

OVERHEAD CONSOLE READING AND COURTESY LAMP
DESCRIPTION
The overhead console in this vehicle is equipped with two individual reading and courtesy lamps. The lamp lenses are the only visible components of these lamps. The reading and courtesy lamp lenses are mounted in the overhead console housing between the compass mini-trip computer display and the sunglasses storage bin. Each lamp has its own switch, bulb, and lens; but both lamps share a common lamp housing within the overhead console.

The overhead console reading and courtesy lamps operate on battery current that is provided at all times, regardless of the ignition switch position. The ground feed for the lamps is switched through the integral reading and courtesy lamp switches or through the door jamb switches. Each lamp is designed and aimed to provide illumination that will be directed only to that side of the vehicle on which the lamp is located.

The reading and courtesy lamp lenses, bulbs and the lamp housing are available for service replacement. The reading and courtesy lamp switches, bulb holders and wiring are only available as part of the overhead console wire harness. If either of the lamp switches or bulb holders is faulty or damaged, the entire overhead console wire harness assembly must be replaced.

For service of the reading and courtesy lamp bulbs, refer to Overhead Console Reading Lamp Bulbs in the Replacement. For diagnosis of the reading and courtesy lamps, refer to Lamp Diagnosis in the Diagnosis and Testing of Lamps.

OPERATION
All reading and courtesy lamps located in the overhead console are activated by the door jamb switches. When all of the doors are closed, these lamps can be individually activated by depressing the corresponding lens. When any door is open, depressing the lamp lenses to activate the lamp switches will not turn the lamps off.

See the owner's manual in the vehicle glove box for more information on the use and operation of the overhead console reading and courtesy lamps.
